Abstract

L'invention a pour objet la production d'une configuration qui peut être facilement réglée de manière à permettre à un volant d'être déplacé de façon stable vers l'avant lors d'une collision secondaire, dont la taille et le coût peuvent être réduits et dans laquelle une charge de séparation peut être réduite et stabilisée. Pour ce faire, un support (12b) côté colonne et une capsule de mise en prise (53), qui sont tous les deux constitués de plaques métalliques, sont reliés et fixés l'un à l'autre par soudage. Deux sections débords gauche et droite (56) sont respectivement disposées sur les extrémités gauche et droite de la capsule de mise en prise (53) par le biais de sections montantes (55). Les deux parties latérales d'une découpe de mise en prise (45) viennent en prise, à l'aide d'une partie d'une plaque métallique qui forme un support (11) côté carrosserie de véhicule, entre les surfaces inférieures des sections débords (56) et la surface supérieure du support (12b) côté colonne de sorte que les deux parties latérales puissent se séparer lors d'une collision secondaire.
